Specification of Letters Patent.

Patented June 24,.1EQ13.

Application filed February 5, 1912. Serial No. 675,542.

. To all whom it may concern:

Be it known that I, AnoLrHUs V. Gnome, a citizen of the United States, residing at Burwell, in the county of Garfield and State of Nebraska, have invented certain new and useful Improvements in-Insect-Destroyers, of which the following is a specification.

The present invention is directed to insect destroyers, and has for its object to produce a device of this character so constructed that an electric current is passed through the bodies of the insects in their attempt to reach the bait, thus instantly killing them.

A further object of the invention is to construct the device in. a simple and practical manner, the same being particularly designed for use in dwellings equipped with electrical wiring.

With these and'ot-her objects in view, the

. invention consists in certain novel features such forinstance, as

The device consists of a hollow-cylindri calbody 1 formed from insulating material, lglass, rubber, wood or papier-machd-theibo y being closed at its upper end by a'cap 1', said cap having an annular. flange 1", which rests upon the upper edge of the body, and has its '"dewires being spirally wound, and in the same direction, the lowertermmals-of said- WII'BS'.

pending gagement with said body. A plurality-of rows of perforations 2 are formed the body 1, said perforations being" alined and vertically spaced, the purposeof which will' be hereinafter described v Suitably secured tolthe upper surface/of the flange lY are binding posts ;3.; Leading from each,binding' 0st and encircling the outer surface of the} ody'l is awire 4, said being secured in the body-1 near the; bottom thereof, thus forminga' finally open circuit. I

The wires 4 are wound" in in parallel relation so that each perforation 2 forming a row will lie in the space between the wires.

ange 2 formed'for threadedem 'such a manner, as to be spaced a-short distance apart and An induction coil 6 is'provided, and leading therefrom are wires 7 which connect to the binding posts 3. The induction coil 6 may be connected to batteries or to a suitable source of electrical energy, as desired.

The device further includes a pan 8, formed from sheet metal. Rising from the center of the pan.8 is a tubular receptacle 9, the same tapering toward its upper end, as indicated at 10, so that the lower end of the tubular body 1 may pass thereover and frictionally engage the beveled upper end of the member 9, to support said body, when the device is to be placed upon a table or other support. As the body 1 and tubular receptacle 9 are frictionally engaged, it is obvious that the body 1 may be suspended from the ceiling of a room in any suitable manner, the frictional engagement between the parts 1 and 9 being sufficient tomaintain their mutual engagement.

. When in use a quantity of bait, preferabl in liquid form ispoured into the recep able 9. The bait referred to may be molasses, honey, or any fluid which tends to attract flies. 1

1 From this construction it will be understood that when a fly is attracted to the device by the odor of the bait passing through per-oration to gain access tothe' bait, alight between the wires. It is "found in practice that thereis a resultant short circuiting of the wires '2 through the body of the fly until el ctrocution of the insect which falls into t e an 8. p

It is vious'from this construction that the same may be usedwith equal success in orchards for exterminating moths and the like, it being only necessary that the bait receptacle and pan be removed and an elec- .tric bulb be placed within the body 1 to attract the insects.

What is claimed is: An electrical insect destroyer, comprlsmg and. secured to the lower end of the body each perforation of each row being positioned between the wires, a cap for closing the upper end of the body saidwires being connected to the cap, and to a source of .1n-

.xdu'ceol electrical energy leading to said cap,

and a bait receptacle having a tapered up- "a hollow cylindrical body having a plurality of rows of vertically alined perforations formed therein, a pair of wires wound spirally around the body in the same directlon,

per end adapted for insertion in the lower end of the body, to close the same so that the fumes from the bait will arise from the re ceptavcle and pass through the perforations to attract the insects to the body, said bait receptacle being supported in a pan for I catching the dead insects.
